So I cleaned up the all the corners and cut a new base. Painted the inside primer white, but left the fan hole piece original black, its an accent wall!
Then I moved stuff around loose forever till finally settling on this footprint. Its not quite what I wanted but its the best I could do without having to cut new front, back, and bottom pieces.
Yes, I installed motherboard standoffs.
I did clone the SATA SSD over to an M.2 SSD so that there are fewer power and data cables. Next step is to route all the power supply cables along the sides, determine if I want to put an intake fan in and if so where. After all that is done, I'll have to mount the "force feedback" solenoids , driver board, etc Last step will be mounting the last piece of wood to the base that the backbox sits on then figuring out all that cabling. I'm still not sure if I should keep the Dell soundbar or put speakers in the cab body.
That GTX1080 GPU isnt staying, the previous GTX 1660Ti goes back in. Its a great card that keeps temps low but can still run VPX like a champ.
As for the hardware upgrade:
Old: i5-3570K 16GB DDR3 256GB SATA SSD
New: i5-8500 24GB DDR4 256GB M.2 SSD
I will likely put another M.2 in this just to be sure I have plenty of room for expansion. I don't see me adding MAME style controls to the lock-down bar like some people do, but I may add a button in the middle if I get enough tables that need it. You may notice I pulled the IPAC2, I replaced it with a zero delay as the IPAC2 is kind of wasted on this build. Another change is that I wont be running power to the start or coin buttons; I prefer to have as little wiring as possible now. I will also be powering the Pin2DMD with a USB cable (plugged into the power strip not the PC) instead of a molex connector for the sake of wiring as well.
Will also probably get a beefier aftermarket CPU air cooler to exhaust air to the back of the cab.
